摘要：区域环境协同治理是近年来中国城市群发展中的关键议题，区域经济协调更是关乎高质量发展的必要因素，两者关系相互交织、相互作用。从区域环境协同治理角度探究促进区域经济发展是新时期推动经济绿色发展、全面推进生态文明建设的重要路径选择。本文以2014年“长三角区域大气污染防治协作机制”这一政策作为准自然实验，选取2003—2019年中国257个地级及以上城市面板数据作为初始样本，运用广义合成控制法，从政策实施有效性视角检验了长三角区域环境协同治理的经济激励效应；采用空间计量模型，从区域环境协同治理状态视角考察了协同度的经济空间溢出影响及传导路径。研究发现：长三角区域环境协同治理对区域经济增长具有显著的促进作用，呈加速态势，分类进行一系列时间安慰剂和稳健性检验后研究结果依然成立。协同度对区域经济增长的影响呈显著的空间溢出效应，长三角区域环境协同治理能够实现对邻近城市经济发展水平的激励，最终实现整体的区域经济增长。科技创新和产业结构均是区域环境协同治理影响经济增长的重要传导渠道。本文建议在长三角区域一体化进程中，需要强化城市的主动协同效应，增强城市的积极性、创造性和能动性，为区域环境协同治理促进长三角区域经济发展提供主体动力。

Economic Effect of Synergistic Environmental Management: An Example of the Air Pollution Control Implemented in the Yangtze River Delta

Abstract: Regional synergistic environmental management has emerged as a key issue in the development of urban clusters in China in recent years, and regional economic coordination is an essential factor for high-quality development. The relationship between the two is intertwined and interactive. Exploring the promotion of regional economic development from the perspective of synergistic environmental management is an important strategic choice for driving economic green growth and comprehensively advancing the construction of an ecological civilization in the new era. This paper takes the Air Pollution Control Implemented in the Yangtze River Delta policy of 2014 as a quasi-natural experiment, selects panel data from 257 prefecture-level cities and above in China from 2003 to 2019 as the initial sample, and employs the generalized synthetic control method to examine the economic incentive effects of the Yangtze River Delta’s synergistic environmental management from the perspective of policy effectiveness. Using a spatial econometric model, it investigates the economic spatial spillover effects and transmission paths of the degree of synergistic from the state of synergistic environmental management. The study finds that regional synergistic environmental management in the Yangtze River Delta significantly promotes regional economic growth, with an accelerating trend, and the results remain valid after a series of time placebo and robustness tests. The degree of synergistic has a significant spatial spillover effect on regional economic growth, where regional synergistic environmental management in the Yangtze River Delta can incentivize the economic development level of neighboring cities, ultimately achieving overall regional economic growth. Technological innovation and industrial structure are important transmission mechanisms through which regional synergistic environmental management affects economic growth, and industrial structure adjustment is the main intermediary transmission path in this impact. In the context of regional integration in the Yangtze River Delta, it is imperative to reinforce the proactive synergy among cities and enhance their positive attributes, creativity, and mobilization. This will serve as the primary impetus for promoting synergistic environmental management and fostering economic development in the Yangtze River Delta.
